output

问题 I am trying to use the CUSP library. I am reading .txt files which are basically sparse COO representation. I am using CUSP to convert into CSR format. When I print the matrix with cusp::print() it prints the correct outcome for COO representation. However when I convert the matrix into CSR, I have written my own function for printing but the outcome is not what I want. Here is the snippet main() { //. //bla bla //.. //create a 2d coo matrix cusp::coo_matrix<int, int, cusp::host_memory> D

问题 I have made a program that can output whatever numeral is inputted in to it but it will convert it to words instead of just numerals for example if you input "1234.56" it will convert it to "One Thousand Two Hundred Thirty Four Dollars and ... 56 Cents". The cents should always be in numerals. So far everything works great, however if I put in an amount that is less that one thousand I will get the excess words such as "Thousand" or "Hundred" in there. For example if I input "15.77" my output

问题 I would like to overwrite a certain line in a txt file while keeping all others the same. Is there a nice and simple way of doing this? 回答1: Basicly use Fseek() to search the sequence of bits that you want to change, then use Fwrite() to overwrite the old text OBS: you need to open the file in rw mode to overwrite fopen ("myfile.txt", "wr"); use those referenses: http://www.cplusplus.com/reference/cstdio/fwrite/ http://www.cplusplus.com/reference/cstdio/fseek/ (it says C++ but works on C) 回答2

问题 I have a fairly large SQL Query that converts a numeric date data type to a date time value and further specifies the search based on my requirements. However when I run this query I'm seeing the column names but there is no data in the columns, it is just the titles of the columns in this order: Dataset, Date, Time, MsgID, Parms, Dataset When the order should be: Data, Time, Dataset, Media (Separate column with Substring of Parms). Also this is only showing my data from the past 2 days

问题 I had saved the required steps for a parameterized string match query that outputs the subsequent rows. I had lost my files when transferring to a faulty drive. So... I'm trying to mash things together and this isn't working. $stmt = $link->prepare("SELECT id,entry,date from table WHERE string=? ORDER by Id DESC"); $stmt->bind_param('s',$string); $stmt->execute(); $stmt->bind_result($id_db,$entry_db,$date_db); if (($result = $link->query($stmt)) { while ($row = $result->fetch_row()){ } } I

问题 I don't know if it's possible: I'm using ffmpeg and I would like to reduce the output of a command.

问题 I need to calculate eigenvalues of a series of matrices and then save them in a separate file. My data has 5 columns and 10,000 rows. I use the following functions: R<-NULL A <- setwd("c:/location of the file on this computer") for(i in 0:1){ X<-read.table(file="Example.prn", skip=i*5, nrow=5) M <- as.matrix(X) E=eigen(M, only.values = TRUE) R<-rbind(R,E)} print(E) } As an example I have used a data set with 10 rows and 5 columns. This gives me the following results: $`values` [1] 1.350000e

问题 In this question I just learned how to illicit one desired element out of a Google translate page. There I have also learned that placing anything into clipboard in Javascript is literately impossible (you can do it by prompting a window asking a user to save some value into the clipboard - but you can't do that automatically), which is a rather sad thing to me as I really need to save that element out of a Google translate page automatically. I wonder if it's at least possible in Javascript
